Real Clear Science published an article lamenting that science can only explain half of the Earth’s internal heat. They believe that the earth’s heat sources are from radioactive decay products and residual heat when the planet was first formed.
Some of the heat is produced by radioactive elements, but there is some really unclear science when they write the following:
The main known sources of radioactivity within the Earth are unstable types of uranium, thorium and potassium – something we know based on samples of rock up to 200km below the surface.
The only rocks that come from those depths are kimberlites, and kimberlites are definitely not radioactive.
So what are the intrepid scientists going to do? Collect sufficient geo-neutrinos to identify which come from uranium, potassium etc.
We must also realise that mainstream science labours under the intellectual weight of Newton’s Gravity theory that has ossified into unchallengeable dogma.
In the previous post I suggested that planets are formed by prolonged plasma Z-pinch mechanisms and if so, and we have a planet like Earth that now has a weak Z-pinch field, (it has to have a weak Z-Pinch field because of the existing plasma configuration), and the previously. highly compressed matter is now slowly changing physical state to a lower pressure, higher volume state. This transition from high pressure, high temperature state to lower pressure and temperature states releases energy, and thus heat.
So the high heat flows from the various spreading zones around the planet are from the outpouring of basalt from a more dense ultramafic parent in the upper mantle. Note that these zones of high heat source are not radioactive, evidence that they cannot have been sourced from a magma heated by radioactive decay.
The other oddity, and it is Wikipedia after all, is the high heat flow ice caps, Antartica and Greenland. Sort of counter intuitive I would suggest. I wonder if it is due to the presence of Chinese fried ice-cream desserts?
Ignoring gravity and using plasma universe physics, then the missing heat is not really a problem – a simple case of the Earth slowly expanding and degassing over time.
Update: Incidentally, a very weak plasma Z-Pinch field surrounding the Earth would result in a very weak Lorentz force that from symmetry would converge to the centroid of the Earth. Some would call this weak force gravity.
